WebDec 28, 2011 · Then you have the so called "informed search" such as best-first search, greedy search, a*, hill climbing or simulated annealing. In short, for the best-first search, you use an evaluation function for each node as an estimate of “desirability". The goal of the greedy search is to expand the node which brings you closer to goal.
